Description

Technical Field

[0001] This utility model relates to the field of biological experimental equipment technology, specifically a double-door independently temperature-controlled carbon dioxide incubator. Background Technology

[0002] A carbon dioxide incubator is a device that simulates the growth environment of cells / tissues in vivo by creating a similar environment within the incubator. The incubator requires a stable temperature (37°C), a stable CO2 level (5%), a constant pH value (7.2-7.4), and a high relative humidity (95%) to culture cells / tissues in vitro. It is an advanced instrument for cell, tissue, and bacterial culture and a key piece of equipment for conducting immunology, oncology, genetics, and bioengineering.

[0003] Most existing incubators use rigid metal trays (without adjustable height), which makes it difficult to flexibly arrange containers of different heights such as culture dishes, culture flasks, microplates, or organoid microarrays. For example, a 150mm culture dish requires ≥30mm of vertical space, while a 6-well microplate only requires 15mm. Fixed-height dividers can easily lead to wasted space or forced stacking, increasing the risk of contamination. When users need to culture samples of different heights at the same time (such as a 60mm culture flask on the top and a 10mm microplate on the bottom), the fixed-position metal trays force the samples to "adapt" to the space rather than "allocate resources as needed." Therefore, we need to propose a dual-door, independently temperature-controlled carbon dioxide incubator. Utility Model Content

[0004] The purpose of this invention is to provide a double-door independent temperature-controlled carbon dioxide incubator, in which the tray is slidably connected to the column via four sets of sliders, and the sliders are equipped with elastic locking components, which can realize multi-level height adjustment of the tray and lock it in place, so as to solve the problems mentioned in the background art.

One side of each of the four sliders is fixedly connected to a tray, and an elastic locking assembly is provided on one side wall of each slider to cooperate with the columns and position the tray. Each cavity of the incubator body is hinged with an independent door, and a magnetic sealing strip is provided on the inner edge of each independent door.

[0008] Preferably, the elastic clamping assembly includes a fixed shell, which is fixedly connected to one side wall of the slider. A movable block is slidably inserted inside the fixed shell. One end of the movable block passes through the slider and is inserted into the inside of the column. The other end of the movable block is fixedly connected to a spring, and one end of the spring is fixedly connected to one inner wall of the fixed shell.

[0009] Preferably, it also includes a pull rod, which is slidably inserted into one side wall of the fixed shell, and one end of the pull rod passes through the fixed shell and is fixedly connected to one end of the movable block, and the spring is movably sleeved on the outer wall of the pull rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A double-door independently temperature-controlled carbon dioxide incubator includes: an incubator body 1, the incubator body 1 being made of double-layer stainless steel shell, a longitudinal partition 2 being provided on the inner wall of the incubator body 1, the longitudinal partition 2 being a vacuum insulation plate, and a receiving cavity 3 being reserved on both sides of the incubator body 1 and the longitudinal partition 2, the inner wall of each receiving cavity 3 being made of 304 stainless steel with electrolytic polishing treatment for easy cleaning and disinfection, a gas circulation module installation interface (not shown) being reserved at the top of the receiving cavity 3, and an independent drain outlet (not shown) being provided at the bottom for draining condensate;

[0025] Each of the two containment chambers 3 is equipped with a temperature control system 4. Each of the two containment chambers 3 has a tray 5 inside. Four columns 6 are fixedly installed on the inner wall of the containment chamber 3. Slider 7 is slidably connected to the outer wall of each of the four columns 6. One side of each of the four sliders 7 is fixedly connected to the tray 5. Elastic clamping components 8 are provided on one side wall of each of the four sliders 7, which cooperate with the columns 6 to position the tray 5. Each containment chamber 3 of the incubator body 1 is hinged to an independent door 13. The inner edge of the independent door 13 is provided with a magnetic sealing strip. The independent door 13 adopts a double-layer tempered glass structure. When the independent door 13 is closed, it achieves airtight sealing through magnetic adsorption. At the same time, a damping device is provided at the hinge of the door to ensure smooth opening and closing without impact.

[0026] The incubator body 1 is divided into two independent chambers 3 by the longitudinal partition 2. Each chamber 3 is equipped with an independent temperature control system 4 and a gas circulation module, which can run different culture parameters at the same time. The tray 5 is slidably connected to the column 6 by four sets of sliders 7. The sliders 7 are equipped with elastic clamping components 8, which can realize multi-level height adjustment of the tray 5 and clamping and positioning, solving the problem of space adaptation limitations.

[0027] The outer wall of the column 6 is provided with a groove 9 that matches the slider 7. The slider 7 is provided with a protrusion 10 that matches the groove 9. The protrusion 10 is slidably connected to the inside of the groove 9. The column 6 is a square aluminum alloy profile, which is vertically welded to the four corners of the inner wall of the receiving cavity 3. The groove 9 is a T-shaped groove with a width that matches the protrusion 10 of the slider 7. The protrusion 10 is made of nylon and is fixed to the back of the slider 7 by bolts. When sliding with the groove 9, the coefficient of friction is low. The slider 7 is a stainless steel stamping part and is fixed to the support plate 5 by welding. The four sets of sliders move synchronously to ensure that the support plate 5 rises and falls horizontally.

[0028] The elastic clamping assembly 8 includes a fixed housing 801, which is fixedly connected to one side wall of the slider 7. A movable block 802 is slidably inserted inside the fixed housing 801. One end of the movable block 802 passes through the slider 7 and is inserted into the inside of the column 6. The other end of the movable block 802 is fixedly connected to a spring 803. One end of the spring 803 is fixedly connected to one side inner wall of the fixed housing 801. In the elastic clamping assembly 8, the fixed housing 801 and the slider 7 are fastened by M4 screws. The spring 803 is made of 65Mn material, with a compression range of 5-15mm, and provides a clamping force of 5-15N.

[0029] It also includes a pull rod 804, which is slidably inserted into one side wall of the fixed housing 801, and one end of the pull rod 804 passes through the fixed housing 801 and is fixedly connected to one end of the movable block 802, and the spring 803 is movably sleeved on the outer wall of the pull rod 804.

[0030] The movable block 802 has a wedge-shaped part 11 at the end away from the spring 803. Several slots 12 that are adapted to the wedge-shaped part 11 are provided on one side wall of the column 6. The wedge-shaped part 11 is inserted into the corresponding slot 12.

[0031] The exposed ends of the four pull rods 804 are connected to each other by connecting rods. The exposed ends of the pull rods 804 are integrated through the connecting rods (8mm in diameter, made of 304 stainless steel). Users can unlock the four locking points simultaneously by holding the connecting rod with one hand.

[0032] Each of the two receiving chambers 3 is equipped with an independent gas circulation module at its top. The gas circulation module includes a centrifugal fan, a CO2 inlet solenoid valve, and a HEPA filter. The centrifugal fan speed is adjustable (0-3000rpm), and it evenly delivers the gas to the bottom of the chamber through the air duct to form a circulating airflow. The CO2 inlet solenoid valve is connected to an external gas cylinder and dynamically adjusts the air intake based on the concentration data fed back by the infrared sensor (accuracy ±0.1%). The HEPA filter is H13 grade, which can intercept particles ≥0.3μm to prevent microbial contamination. The humidity maintenance unit is an ultrasonic humidifier, which maintains the humidity in the chamber ≥95% by atomizing water vapor.

[0033] The temperature control system 4 includes a water-jacketed heating unit and an air-jacketed heating unit. The water-jacketed heating unit is located in the side wall interlayer of one receiving cavity 3, and the air-jacketed heating unit is located in the side wall interlayer of another receiving cavity 3. Both heating units are electrically connected to independent PID temperature controllers. The water-jacketed heating unit is embedded in the interlayer of the left receiving cavity 3, which is filled with deionized water and heated by an electric heating rod. The water temperature is regulated by the PID temperature controller (temperature control accuracy ±0.1℃). The air-jacketed heating unit is located in the interlayer of the right receiving cavity 3 and uses ceramic heating elements to directly heat the air. Rapid heating is achieved through forced convection by a fan (heating rate ≥3℃ / min). The two PID temperature controllers operate independently, receiving signals from the PT100 platinum resistance temperature sensor in the cavity and dynamically adjusting the heating power through the PID algorithm to ensure temperature stability.

[0034] Working principle: Users can set the temperature, CO2 concentration, and humidity parameters of the two chambers 3 through the control panel. The left chamber uses a water jacket heating system, which is suitable for long-term stable culture such as cell culture at 37℃. The right chamber uses an air jacket heating system, which is suitable for experiments that require rapid temperature rise and fall, such as heat shock reactions. When the chamber temperature is lower than the set value, the PID controller starts the water jacket or air jacket heating unit, and at the same time, the centrifugal fan drives the airflow to circulate, ensuring temperature uniformity. The CO2 concentration is monitored in real time by an infrared sensor. The controller adjusts the air intake through a solenoid valve. Excess gas is discharged through the exhaust port, purified by the HEPA filter, and re-enters the circulation. The ultrasonic humidifier automatically starts and stops according to the feedback from the humidity sensor to maintain a high humidity environment.

[0035] When the height of the pallet 5 needs to be adjusted, the user pulls the connecting rod 14. The four sets of pull rods 804 simultaneously drive the movable block 802 to compress the spring 803, so that the wedge part 11 disengages from the slot 12. The pallet 5 can slide freely along the column 6 to the target position and then release the connecting rod. The spring 803 pushes the wedge part 11 to re-lock into the slot 12.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
